To all whom it may concern..-

Be it known that I, J OHN S. PETER, of An; gelica, county of Allega'ny,New York, have invented a new and Improved Lubricator and Measure, ofwhich the following is a full, clear, and exact description.

The principalobject of my invention is to provide a lubricator ofsimple, inexpensive, and durable construction, and which shallautomatically feed oil or other lubricant in. measured quantities to thevalves of locomo tive-engines, when or after the steam is shut off byclosing the throttle, aslightly-modified construction being applicableto the measurement of liquid or other substances.

The invention consists in an arrangement of a movable platein themeasuring-chamber,

which latter connects by passages with the cup or'reservoir'oi' anoutlet'ther'efrom'fsaid passages being suitably valved to controltheflow to and dischargev from the'measuring chamber. i

The invention includes, also, special con-j.

structions and combinations of parts of the device, all as hereinafterfully described and claimed;

Reference is to be ,had to the accompanying drawings, forming part ofthis specification, in

' which similar letters of reference indicate corresponding parts in allthe figures.

Figure 1 is a vertical sectional elevation of a lubricator embodying myimprovements. Fig. 2 is a horizontal section on the line as a, Fig. 1;and Fig. 3 is a vertical sectional elevation of my invention in part,and as applied to a measure.

Referring first to Figs. 1 and 2 of the draw- .ings, the letter aindicates the oil cup. or reservoir of the ,lubrieator, havingany'suitable removable plug, 1), at the top, closing an aperture throughwhich the oil may be filled into the cup. The cup a has an aperture at cin its bottom, preferably at the center, and a depending neck, d, whichhas or may have a separable bottom plate s, fixed thereto, said plate ebeing centrally aperturcd at f, in line with aperture 0 andconcentrically with the neck cl. The. apertures c f and the neck (1 haveinterior serew-threads formed in them of like pitch to receiveaserew-plug, which con- SiStS of a neck,g, entering aperture 0, ascrewplate, h, fitting the neck d, and a lower 'neck portion, 6; whichfits thethreads of the aperture f of plate 6, so that after the neck-gand plate 71 have been screwed into place the plate e may be screwedonto the neck i and against the lower edge of the neck d, where saidplate 6 is secured rigidly by screws or other means.

The neck cl forms the side walls of the oilmeasuring chamber, the bottomof the cup a forms the top of the chamber, and the plate h its bottom orfloor. In the neck 9 is fitted a double plug-valve, j, having upper andlower heads, '70 Z, respectively, which seat themselves alternately atthe top of neck 9 and at the bottom of the plate h. The valvesteinchamber or bore m of neck 9 has passages a, leading therefrom and fromthe interior of the cup a to the measuring-chamber 0,

the stembf'the valve being shaped to allow free flow of the oil from-cup a to the chamber 0 when valve l-is closed andvalvek open, and fromthe chamber 0 throughthe passages chamber 0; and when thethrottle -valveis closed and the steam is shut oh, the valve 75 will close to cut offthe flow from,. cup a, and the valve Z will open and allow" the oil thathad previously entered the chamber 0 to escape to the steam chest r,tolubricate the valves when they are moving over their seats while theengine is slowing down or stopping; hence the valves receive oil wher.

they are not lubricated by the steam, and when when effectivelubrication is most needed.

, It evident that by screwing the cup on up or down the, oil-chamber 0may be enlarged or contracted at will. by the lowering or raising of theplate h relatively to the neck d,- i (l hence the quantity of oil to becharged to the valves at a time may be accurately measured, and seriouswaste of 011 prevented. By screwing the bottom of cup to down to plateh, all

, voir, as a tank, cask, or other vessel,-and the nieasuringchaniber oto fill, are lifted by a flow of oil from the cup will be prevented. Imake either valve k or 'Z-prei'erably the valve kadjustable along thevalve-stem, and secure itby a janrnut, t, or other device, so that theflow of .oil from. the cup a may be controlled by regulating thedischarge through the valve It, as will be readily understood; orboth'valves may be adjustable on the stern, if desired.

In the modification shown in. Fig. 3, the screw-neck g is fixed,by a pinor screw, y, .to the outlet a from any liquid or other reserplate It isfitted to the interior threads of the invert-ed cup d, which is fittedto the threads of the neck (j, and has any suitable upwardlyclosing ventplug or valve or device at u, to insure discharge of the liquid from theincasuriug-ehamber 0, through the passages 11, past the valve], whenopen, and through neck 5 into any vessel placed below to receive theliquid. In this case the nut tis applied at the lower valve, Z, and thevalves 7c 6, instead of being lift-ed by steam-pressure,to allow thepivoted and weighted elbow-lever, I, which has a pin and slotorlothersuitableconnection at in with the stem j of the valve, said steml passing through a striding-box at x in the out let a. \Viththelevcr'vin the position shown, the chamber 0 will be filled, and whenthe el: bow-lever is swung over on its pivot toward the right hand thehow from a will be cut oil, and the measured liquid or-substance in thechamber 0 will be discharged, The capacity of the lubrieator or measurewill vary with the diameter and length of the neck or cup 01 or d.

I have shown theluln'ieator-cup u arranged directly over the neck d andplate la as best I suited for direct connection with the valve chests0flOCOll'lOiQlVQ-(lllgiilOS; but the oil-eup i ma be in the en ine-caband have an outlet lower edge ol' the cup '11, as shown in Fig. 3

of the drawings.

.llaviug thus described my invention, Iclaim as new and desire to secureby Letters latent l. The coml'iiuation. with an oil-reservoir,

of a nreassuring-chamber provided with an adjust-able bottom havinginlet and outlet passages, and valves for alternately closing andopening said iuissages, substantially as here in shown and described.
